NoteGenerator for Mac vs Granola: Bot-Free Isn't the Same as Local

At a glance

Bot-free vs local: the one-line difference

"Bot-free" and "local" get used as if they mean the same thing. They don't. Bot-free answers one question: does a separate attendee — a recorder bot — join your meeting? Local answers a different one: does the conversation leave your device at all?

Granola is bot-free. Its Security page states "It does not add a bot to your video call," and its FAQ says "No bot joins your meeting — other participants will not see any additional attendee" (granola.ai/security, July 2026). NoteGenerator for Mac is bot-free too. The difference is what happens after capture: with Granola, the audio is sent to third-party cloud providers to be transcribed and summarized, and the transcript and notes are stored in Granola's US cloud; with NoteGenerator, all of that happens on your Mac.

What Granola does well (and we mean it)

Granola is a well-built, bot-free cloud notepad, and its strengths are real. It captures audio without putting a bot in your meeting, so other participants see no extra attendee (granola.ai/security, July 2026). It does not retain your audio: the Security & Privacy FAQs state audio is "deleted from our systems and any third-party services" once transcription is complete, and the Privacy Policy states "We do not retain or store such recordings once the transcription is created" (effective 24 July 2026). It runs across macOS, Windows, and mobile, syncs your notes, and keeps them private by default until you choose to share (granola.ai/security). And it publishes an enterprise-grade posture: SOC 2 Type 2, encryption at rest and in transit, a US-hosted AWS Virtual Private Cloud, and a commitment that third-party AI providers may not train on your data (granola.ai/security).

If those properties meet your bar, Granola is a genuinely good tool. This page is about one specific axis where it differs from NoteGenerator: whether the conversation stays on your device.

Where your audio actually goes

Bot-free is a statement about the meeting, not about your device. Granola's own Security page explains that it "uses best-in-class transcription providers (like Deepgram and Assembly)" to produce the transcript and "AI providers (like OpenAI and Anthropic) to summarize your meeting" (granola.ai/security, July 2026). Its Security & Privacy FAQs state that audio is "temporarily cached during the meeting for transcription only" and, once complete, "is deleted from our systems and any third-party services" (July 2026).

So the audio is captured on your Mac but sent off-device to third-party cloud providers to be turned into text — in real time on macOS and Windows, or after the meeting from temporarily cached audio on mobile (granola.ai/security). Granola's honest, documented promise is that it doesn't keep the audio. NoteGenerator's promise is a different one: the audio never leaves your Mac in the first place, because transcription runs on-device.

Where your transcript and notes live

Granola does not keep your audio — but it does keep your transcript and notes. Its Security page states "Notes are stored in our US-hosted AWS Virtual Private Cloud" and are "encrypted at rest and in transit," and its Privacy Policy states "we store your Personal Data in Amazon Web Services (“AWS”) servers located in the U.S." (effective 24 July 2026). Notes are private by default until you choose to share them, and you can delete individual notes or request deletion of all your data at any time (Security & Privacy FAQs, July 2026). Granola names Deepgram, Assembly, OpenAI, Anthropic, AWS, and Stripe among its providers, and its Data Processing Addendum points to trust.granola.ai/subprocessors as the authoritative list (Granola DPA, last updated 17 July 2026).

The text of your conversation lives in Granola's cloud. With NoteGenerator, the transcript and notes are written and stored on your Mac — encrypted at rest with AES-256, the key held in the macOS Keychain — so there is no server-side copy at all.

Model training: what's on by default

By default, Granola uses your data to improve its own models — with an opt-out. Its Security page states: "Granola trains on your anonymized data so we can keep making Granola better. You can opt out of this in your Settings. Enterprise users have model training turned off by default." Its Privacy Policy adds that it uses "de-identified data to train AI models, which you can opt-out of within your Granola account settings," and that "Enterprise Workspace Products ... are opted-out by default" (effective 24 July 2026). Granola also states it does not allow third parties like OpenAI or Anthropic to use your data to train their models (granola.ai/security).

So on non-Enterprise plans, training on de-identified data is on unless you opt out; on Enterprise it is off by default. With NoteGenerator there is no cloud copy of your notes to train on — the note-writing model runs on your Mac, and there is no account tied to your name or email.

How NoteGenerator is different: on-device by default

NoteGenerator for Mac takes a different architecture. After a one-time model download, recording, transcription, AI note-writing, and encrypted storage all run on your Apple-silicon Mac — it works with Wi-Fi off.

"Nothing leaves your Mac" is true after that one-time setup, with a few named, content-free exceptions: the initial model download; a license or trial check (a one-way device code and a device identifier we treat as personal information — never your name, email, or note content); update checks (on by default, with an off switch); and any links you choose to open. Your recordings and notes are encrypted at rest with AES-256, the key held in the macOS Keychain; the app is notarized and sandboxed.

The trade-offs are real and we state them plainly: NoteGenerator runs only on Apple silicon (M1 or newer), the AI-written note needs about 16 GB of RAM (with less, you still get the transcript), and the model download takes several GB of disk. It is a single-user Mac app — no Windows, no mobile, no team sync.

Provable, not just promised: the Seal Test

You don't have to take our word for it — but be clear on what the proof shows. NoteGenerator includes a live connection counter that reads 0 when the app is sealed, and a one-tap Seal Test: the app deliberately tries to open a network connection to itself, and you watch it be stopped before it reaches the network.

That demonstrates the app opened no outbound connection during your session on that machine. It is a check you run yourself — not a claim that the binary can never connect under any condition, and not a guarantee about everything else running on your Mac. It verifies the app's own network path, in your session.

Granola offers a different, complementary kind of assurance: it states its practices meet SOC 2 Type 2 standards, verified by independent auditors (granola.ai/security, July 2026). That is a third-party audit of its cloud practices rather than a test you run on your own machine. Both are legitimate; they answer different questions.

When Granola is the better choice

Granola is the better choice in several real situations.

• You work on Windows or mobile. Granola runs on macOS, Windows, and mobile (granola.ai/security, July 2026); NoteGenerator is Apple-silicon Mac only.
• You want cloud sync and sharing. Granola keeps notes on every device and lets you share with teammates when you choose; NoteGenerator is single-user and on-device.
• You want zero setup. Granola is a managed service with no local model download and no 16 GB RAM requirement.
• You want an enterprise cloud-security posture. Granola publishes SOC 2 Type 2, encryption at rest and in transit, a US-hosted AWS VPC, third-party AI providers barred from training, and model training off by default on Enterprise (granola.ai/security; Privacy Policy, effective 24 July 2026).

If your bar is "no bot in the meeting, a SOC 2 vendor, audio not retained, and third parties barred from training," Granola's bot-free cloud model is a genuine fit. NoteGenerator is for the narrower case where the conversation must never leave your device — and you want to verify that yourself.

Verify it yourself, in five minutes

Whichever tool you choose, you can check its network behavior yourself. Turn on Airplane Mode and see whether note generation still works. Watch outbound connections with a network monitor such as Little Snitch or LuLu, or with macOS's own Activity Monitor.

Because Granola's transcription and summarization run in its cloud (granola.ai/security, July 2026), it needs a connection to produce a note. A local tool like NoteGenerator should keep working with the network off — and its Seal Test lets you watch its own path stay closed. Our guide, How to verify an AI note taker is actually offline, walks through the general, tool-agnostic method step by step.
